Worked Solution & Example Answer:The diagrams show the mass and weight of four objects (A, B, C and D) on the Earth, Earth’s Moon, Jupiter and Venus - Junior Cycle Science - Question f - 2019
Step 1
Which object, A, B, C or D, has the smallest mass?
Answer
To determine which object has the smallest mass, we can look at the weights given for each object on Earth. Object C has a weight of 25 N, which corresponds to an 1 kg mass using the formula:
In this case, the gravitational field on Earth is approximately 10 N/kg, so:
Objects A and B are heavier, and object D also has a higher weight. Therefore, object C has the smallest mass.
Step 2
How can you tell that the force of gravity is less on Venus than it is on the Earth?
Answer
We can tell that the force of gravity is less on Venus than on Earth based on the weights of objects of the same mass. For example, an object with a mass of 8 kg weighs:
- 80 N on Earth
- 72 N on Venus
Since an object weighs less on Venus, we can conclude that the gravitational force acting on it is weaker compared to that on Earth.
